1) soak crushed pills in first in NP solvent and then acetone; filter, repeat 3 times or more for each solvent
2) dissolve in lots of water, acidify with a little HCl or H2SO4
3) let insolubles settle out at least overnight in a high and narrow container; 24hrs or longer might work even better
4) heat decanted/filtered solution close to boiling point, scoop out shit that might come out of solution
5) extract with non-polar, discard the wash
6) basify with NaOH
7a) extract freebase with NP, evap NP to obtain pseudo freebase
In case of horrible emulsion formation:
7b) remove FB by filtration, extract filtercake with hot NP, let evaporate to obtain freebase
